GETTING STARTED?

[human fly]

hi folks: newbie post:

since i couldn’t find a topic on ‘getting started’ – but did find someone asking how to
on another thread – i thought i’d start it myself.

i have some experience with sysex, but no idea how to get started with ctrlr, and there’s
no manual yet.

any tips on making first steps or a very simple (single object?) project would be a great
help. also best way to set up to work with it, what other resources needed, etc.
thanks.

probably the most important thing to know about CTRLR is the xx variable.

when you add a control, ie; a slider or button…. you tell the control
what value you want to send using the xx variable.

for example, setting a control with a range of 0 – 127 will
give xx a value of 0-127 in a midi message like : F0 11 22 43 09 xx F7 plugged into the control’s midi message box

good luck and have fun making CTRLRS!!!!!

I am a newcomer to Ctrl (this is my first post).
My first "Hello World" is a Tooggle Button to ON/OFF GM Mode in a Roland Jv2080

I need to send [F0 7E 7F 09 01 F7] (GM ON) or [F0 7E 7F 09 02 F7] (GM OFF)

From the upper example, I configure the modulator (Tooggle Button):

MIDI MESSAGE TYPE: 5 – SYSEX
SYSEX FORMULA: F0 7E 7F 09 xx F7

But, where I configure the "real" values (01 , 02) to pass to xx?
Where to assign values 01 and 02 to the two positions of Toggle Button

(my "Hello World" sends xx=00 and xx=01, not 01 and 02)

---

More questions:

What is exactly ‘xx’?. I think is a variable value controled via modulators, used by internal code of Cntrl to create SYSEX strings).

Ok, there is more ‘named’ variables (example from JP8080 panel):
F0 41 10 00 06 12 01 00 k0 32 xx z5 f7

k0: I think is a global variable (there are, by inspection, k0 to k16). Are they global to a individual panel o to all panels open?

xx: I think is the same

z5: usually this byte is CHECKSUM for ROLAND SYSEX Mssgs. Where is it calculated? Internal code not accesible?
There is a z0, z1, etc, etc?

Are more ‘named’ variables I need to know?

Sorry if the question seems too dumb.

Solved using a slider with only two possible values (min = 01 and max = 02)

But, no luck how to pass values to a toggle or ON/OFF button, if posible.

Any help?

I think I only need to understand a small question to start making my firsts experimental panes.

By example, taken from the Jp8080 panel, a slider sends this SYSEX:
F0 41 10 06 12 01 00 k0 29 xx z5 F7

No problem how to asign value to xx (from modulator config params)

But I don´t know how/where/configure to assign values to global variable

k0 (by midi monitoring, value=40)

and to calculate CRC value and assign it to z5 (checksum for maybe all Roland Synths)
LUA method? But I can´t find it.

any help to overcome this brief difficulty, please

(My excuses for the language, I don´t speak in english)

Those tokens are inside Ctrlr they are pre-assigned, the checksum counts 5 bytes from it’s position and calculates the checksum of those 5 bytes, after that it inserts the resulting checksum at the position of the z5 token (theese are tokens that’s what i called them).

The k0 to kf are global values you can assign in the panel, you can create a modulator that will change the value of one of the 16 global values thus changing the sysex that will be sent that has the k0 (or any other k token) token. k0 and kf cause they’re hex
[code:19tuqj89]
k0 k1 k2 k3 k4 k5 k6 k7 k8 k9 ka kb kc kd ke kf
[/code:19tuqj89]

why z,k,x,y,ls,ms cause they’re not HEX and i can distinguish a hex value from a token and apply an action to it.

Ok. Verified . Fantastic!!!
Thanks.

oppps, Can you solve this little previous question?

I am a newcomer to Ctrl (this is my first post).
My first "Hello World" is a Toggle Button to ON/OFF GM Mode in a Roland Jv2080

I need to send [F0 7E 7F 09 01 F7] (GM ON) or [F0 7E 7F 09 02 F7] (GM OFF)

From the upper example, I configure the modulator (Toggle Button):

MIDI MESSAGE TYPE: 5 – SYSEX
SYSEX FORMULA: F0 7E 7F 09 xx F7[/i:3mlqjea8]

[b:3mlqjea8]But, where I configure the "real" values (01 , 02) to pass to xx?
Is possible to assign values 01 and 02 to the two positions of Toggle Button (or other values)?[/b:3mlqjea8]

Yes there are two properties for the toggle button "Value for ON state" and "Value for OFF state".

Yes, I have used previously these properties but no luck (the button always sends 00 or 01 values)
Maybe I need to modify another properties, additionally?
